Patented Dec. 5, 1933 UNITED STATES PATENT OFFICE 1,938,199 CURVED-EDGE WINDOW ORGANIZATION Trygve Vigmostad, Detroit, Mich., assignor to The Murray Corporation of America, a corporation of Delaware elements serving as frames for window openings therein; and it is an object of the present invention to provide, for use in such doors, a window having a curved leading edge and provided with a substantially arcuate or suitably curved guide therefofi-said edge and said guide being so disposed as substantially or entirely to obviate uncovering of any portion of said edge opposite a slightly acute but rounded angle provided at the lower front corner of the window opening.

In preferred embodiments of the invention, a rearward edge of the mentioned window being optionally provided with a curvature substantially parallel with or generally similar to that of the mentioned leading edge, and the top and bottom edges of said window being preferably substantially horizontal and parallel, a doublearm regulator of a known type may be so employed as to maintain the horizontality of the mentioned top and bottom edges during a raising and lowering of said window while nevertheless permitting said window to freely respond to the guidance of the suitably curved channel element,-adapted respectively to receive the leading and the rearward edge of said window and to cam the window forward and back during lowering and raising movements thereof.

Other objects of the present invention, in which use may be made of guides which comprise resilient portions, and/or which have but limited and/0r varying areas or lines of cooperative engagement with the mentioned window edges, may

. be best appreciated from the following description of an illustrative embodiment of the invention, taken in connection with the appended claims and the accompanying drawing.

Fig. 1 may be referred to as an inside elevational view of a right-hand door of an automotive vehicle, parts being broken away and cooperating members being omitted.

Fig. 2 is a horizontal sectional detail view, taken substantially as indicated by the line 2-2 of Fi 1.

Referring first to general features, the illustrated door comprises an outside panel 10 and an outside panel 11, extending substantially parallel with one another and secured together by Z-section frame elements 12 of a known type; and the mentioned parts may be said to cooperate in the provision of a sash or'frame for a substantially trapezoidal window opening. The latter includes,

in addition to an inclined leading edge 13 (shown as deviating less from perpendicularity than does the corresponding edge portion 14a of the leading edge of said door), a rearward edge 15, and substantially horizontal top and bottom edges 16 and 17. A rearward edge 18 of said door being shown as substantially vertical, as seen in elevation, a portion 14a of the mentioned leading edge is shown as meeting a lower portion 14b of said edge in an obtuse angle 14. This is shown as adjacent a slightly acute but rounded angle formed between the edges 13 and l? of the window opening; and the problem to which the present invention is directed may be understood to relate to an avoidance of an uncovering of any portion, or of any considerable portion, of the edge 13, in the region of this angle, or any uncovering of a forwardly curved leading edge 13' of a window 19, movable relatively to said opening. The window 19 may be raised and lowered by means of a double-arm regulator 20, of a known type, adapted to maintain the horizon tality of top and bottom edges 16 and 17 of said window while permitting a limited advance and retraction thereof under the control of special guidance means including a suitably curved guide or guides.

Drawn as a chord relatively to a curved forward guide 21, a dot-and-dash comparison line 22 is shown as extending between the position occupied by an upper front corner of the window 19, when closed, and the position occupied by a lower front corner of said window when open; and it will be seen that an elimination of mentioned curvatures and a guidance of the window 19 in a path parallel with the line 22 (as, by a straight channel element similarly extending across an angle in the forward edge of the door) would tend to expose at least a portion of the edge 13' in the region of the upper front corner of the window 19, whenever said window is lowered to or below a position such as that in which it is shown in full lines. To obviate this elfect, a portion of the forward edge 13, between the mentioned forward corners, is given a forward convexity sufficient to enable the window 19 at all times to overlap the edge 13 even in the region of the angle formed between said edge and the edge 17; and the guide 21, preferably serving as a cam, may be given, at least in the central portion thereof, a forward curvature suitable to the effect here referred to.

To obviate exposure of the upper portion of a rearward edge 15 of the window 19 upon a lowering of said window from a position in which its top edge occupies the level indicated by the line 16 through a position indicated by line 16' and line 17' and to a position indicated by the line 17'], the edge 15' may advantageously have a curvature generally similar to that of the edge 13'; and the edge 15' may advantageously be received in one or more guides curved similarly to the mentioned guide 21, at leastin the central portion thereof. Neither an exact concentricity or an exact parallelism of curvatures in guides for the edges 13' and 15' of the window 19 would be entirely favorable to the indicated mode of operation in case the guides were entirely rigid throughout the length thereof and the edges 13 and 15 were in continuous engagement with the bottom thereof; and even though a central portion of the guide 21, be somewhat rigidly supported (as by the contact with the Z-section element 12 and/or a suitable bracket or brackets 23, 24) terminal portions 21a, 21b of the guide 21 may advantageously be so resilient or so supported as to permit a limited deformation of at least the bottoms thereof incidentally to the raising and lowering of the window 19. An analogous construction may be employed in the case of a rear guide 25 comprising resilient or other terminal section 25a, 25b and shaped to, receive the rearward window edge 15',-brackets 26 and27 being shown as securing the last mentioned guide at two levels only.

Loosely referring to the curved lines provided by edge 13' and guide 21 as arcs and to the dotand-dash line 22 as a chord, it will be seen that the center of said chord may fall substantially at the level of the forward extremity of the rounded angle between edges 13 and 17,the exact curvature of any prominence provided by edge 13 being dependent upon the angle referred to and /or that obtuse angle in the forward edge of the car door across which the chord 22 extends; and, as to mode of operation, it will be understood that manipulation of an inwardly exposed crank 28 of the double-arm regulator 20 is effective, by engagement of cam fingers 29 within a horizontal slot 30 in a glass-receiving connection element 31 'adjacent the lower edge 17 of the window 19, to raise and lower said window in a manner permitting the latter to float in a fore-and-aft direction and under the control of guidance means such as provided by the channels 21 and 25, parts thereof serving as cams; and that the curvatures and resilient properties of said channels, where cooperating with curved prominences in edges 13 and 15 of the window 19, are such as to obviate or minimize any uncovering of the lastmentioned edges incidentally to the raising and lowering of said window.

Although the foregoing description has included complete details of but one embodiment of the present invention, it should be understood not only that various features thereof might be independently employed but also that numerous modifications, additional to any suggested herein, might easily be devised by skilled workers, if informed of the foregoing-all without departure from the scope of the present invention, as the latter is indicated above and in the following claims.
